When wildfires choked the air and turned the skies orange throughout the West in recent years, they caused a variety of health problems from coughs and runny noses to life-threatening heart attacks and strokes. But eczema and other skin issues were a result of the wildfires, too, according to researchers from the University of California, San Francisco (UCSF), and the University of California, Berkeley. "Skin is the largest organ of the human body, and it's in constant interaction with the external environment. So, it makes sense that changes in the external environment, such as increases or decreases in air pollution, could affect our skin health," said Raj Fadadu, a student in the UC Berkeley-UCSF Joint Medical Program.
